MODE OF CONSTRUCTIIVG METALLIC ROOFING.

Specification of Letters Patent No. 11,292, dated July 11, 1854.

To all whom it may concern:

Be it known that I, HENRY OUTCATJI, of Vilmington, in the county of Clinton and State of Ohio, have made certain new and useful Improvements in the Manufacture of Metallic Roofing; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this description, in which Figure 1, is a cross sect-ion taken in the m, Fig. 3. Fig. 2, is across section taken in the line y, y, Fig. 4:. Figs. 3. and 4, are plan views of broken sections of my roofing. Fig. 5, is a plan view or diagram showing the manner in which the plates are cut at their ends, 620. Figs. 6 and 7, are diagrams showing the manner of interlocking the ends of the plates.

The nature of my invention consists in constructing a metallic roof which will not be. affected either by expansion or-contraction, and at the same time it is rendered perfectly water proof in every particular and it may be made when required so that it will suspend its own weight and that of any superfluous body suchas snow or other sub stances that may accumulate under any c1rcumstances without the aid of rafters or other support, of any kind.

In order to enable others skilled in the art to make and use my-invention, I will now proceed to describe its construction and operation.

The sheets of metal of any convenient size may be cut in the manner seen in Fig. 5, that is the ends are cut alternately in opposite directions, and the tongues thus formed, are bent over in the form of a hook as seen in Figs. 6 and 7, but before this is done the edges of each plate are scrolled or rolled up in the manner seen at b b Fig. 1. Next I take a narrow strip of the same material and scroll it in the same manner but thescroll must be a size larger and one end should be slightly larger than the other so as to allow these ends to be easily matched together. I also have a different manner of matching the edges of the sheets together as seen in Figs. 2 and 4:, where the edges of the plate are rolled in opposite direoticns; and

one scroll is slipped over the other as seen at d, Fig. 2. This manner of connecting the plates togetheris far cheaperthan the other and is equally good where roofs are supported by rafters in the ordinary way.

But in cases where it is desirable to construct a cheap and durable fireproof roof, it can be done most effectually in the manner first described.

Having fully explained the manner of preparing the sheeting for use, I will now proceed to describe the method of using it, and thus briefly show some of its most prominent advantages over the ordinary method now in use.

I commence at thelower edge of the roof, and lay one course the whole length of the eaves, and secure them at the lower end in any convenient manner. I then commence a second course directly above the first. The

lower end of the second course slides over 7. The lower end of the scroll is also slid over the upper end of the scrolls on the first or lower course. Then this is done the lower end of each plate may be secured as most convenient and thesame process may be continued until the work is completed. The apex of the roof and the ends may be finished in any style best adapted to the nature of the building.

The above process of laying my roofing applies more particularly to that described in Figs. 2 and 4.

The manner of laying the suspension roofing is as follows: Sections of the sheeting, 7", may be put together which are long enough to extend the whole'width of the roof, and the upper and lower ends may be secured firmly in a proper position, and just far enough apart to admit of a scroll 0 being slipped on over the two inner scrolls as seen in Fig. l. Scrolls 0 may be connected together in the same manner as the plates, but care should be taken to break joints, as it will add greatly to the strength of the roof. After they have been put together, the outer scroll may be slipped over the whole length of the inner scroll, and thus the work may be continued untilthe roof is completed.

The advantages of my roofing are, 1st, the facility with which I overcome the disadvantage of the contraction and expansion.

These disadvantages have long stood in the way of using metallic roofing. Theyare too common and obvious to need any explanation. t will be readily seen that my process efi'ectuallyiobviates this difliculty and makes a roof that is entirely water proof without securing the edges in any permanent position. It will be perceived by the drawings that there is ample room for contraction and expansion in either direction, as the plates are secured only in one place and that is at the lower end of each plate. It will also be observed that if the rain drives under the scroll in the direction of the arrow, 1, it cannot possibly enter the roof because it will be carried by the scroll completely over, and then left to run out again or be carried off in the scroll. The object in cutting and bending the plates as seen in Figs. 5, 6, and 7, is to prevent the water from driving under the lower end of the plate. When the plates are interlocked the corners of the tongues project past each other in such a manner as to eflectually prevent the passage of any water under the end of the plate. The great advantage presented in my metallic suspension roof are, 1st, its great strength and durability; 2nd, the ease and facility which any damaged sheet or section may be removed, in case where a sheet becomes damaged it is necessary to remove it, and replace it by inserting another in its stead. To do this it is only necessary to slide the injured sheet up until the lower end can pass the upper end of the plate next below it. Then by drawing the sheet down a short distance it will easily slip out, and another plate can be inserted by reversing the process.

I do not claim merely scrolling the edges of metallic plates and thus connecting them together for the purpose of preventing water, from driving through the roof, as that is an old device. But

What I do claim as my invention and desire to secure by Letters Patent is Scrolling the edges of metallic plates, so as to form a tube or cylinder, and then connecting their edges by means of other scrolls which are formed also into tubes on the edges of a narrow strip of the same Kind of plate, and being somewhat larger than the former tube, or scroll. So that they will slide over and fit snugly to it for subserving three different purposes, viz., first for protecting the roof against injury, from contraction and expansion, second for the purpose of preventing the water from driving through the roofing at the scrolls,

third for the purpose of supporting the roof and all superfluous weight that may accumulate such as snow, &c., without any superstructure other than those on which its ends rest, the whole being arranged and constructed as described.

Signed and sealed in presence of two witnesses.
